Texas's 28th congressional district of the United States House of Representatives covers a strip in deep south Texas starting in the eastern outskirts of San Antonio, and ending at the U.S.–Mexico border. Towns entirely or partially within this district include Converse, Laredo, Rio Grande City, and Universal City. TX-28 includes The Alamo, a historic monument in what is now downtown San Antonio that plays a central role in Texas' identity. The current Representative from the 28th district is Henry Cuellar.

The district was one of 13 congressional districts that voted for Donald Trump in the 2024 presidential election while simultaneously electing a Democrat in the 2024 House of Representatives elections.

Recent election results

2004 election

2006 election On June 28, 2006, the U.S. Supreme Court declared that the Texas legislature's redistricting plan violated the Voting Rights Act in the case of Texas's 23rd congressional district. As a result, on August 4, 2006, a three-judge panel replaced district boundaries for 2006 election for the 23rd district, which affected the boundaries of the 15th, 21st, 25th and 28th districts.

On election day in November, these five districts had "jungle primaries": any candidate that receives more than 50% of the vote wins the seat. Otherwise, a runoff election in December decides the seat.

Cuellar retained his seat in the 28th district.
